Encryption is the most important method in transferring data through internet and cellular phone. Due to increasing incidents of cyber-attacks, the demand for effective internet security is increasing. Cryptography is the science and study of system for secretes communication. Cryptography is used in applications like security of ATM cards, computer passwords, electronic commerce, telemedicine, e-health, telecommunication, and so on. In this paper, an encryption and decryption method is proposed to generate offspring of multimedia data using operations analogous to biological processes.
